BUILDING CONSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 438,678, dated0ctober21, 1890.

Application filed April 4, 1890- Serial No. 346.585 (No model.)

T0 at whom it may concern.-

Be it known that I, HARRY D. BUSH, of New York, in the county and Stateof New York, have invented a new and useful Improvement in BuildingConstruction, of which the following is a specification.

The object of my invention is to improve the manner of constructingpartitions from boards or slabs such as those described in Patent No.386,102, dated July 10, 1888.

I will proceed to describe the form in which I prefer to embody myinvention, and more particularly point out its essential features in theclaims.

Figure 1 represents a partly-constructed partition wall, with the floorand ceiling beams in side view. Fig. 2 represents a vertical section ofthe same. Fig. 3 represents a horizontal section of the same. Fig. 4represents details enlarged. Figs. 5, 6, 7, 8, and 9 represent certainmodifications.

a is the ceiling-beam, to which the studs are attached at the top. I) bb are the floor-beams, to which the studs are connected at theirbottoms.

c c c c are the studs. The most simple form of these studs is shown inFigs. 1 to 4, inclusive, consisting of a single piece of iron containinga web (1, from one extremity of which projects at right angles theflange e, and from the other extremity of which projects in the oppositedirection at right angles the flange f. Instead of being constructed ofa single piece of iron, the studs, however, may be constructed as shownin Figs. 5, 6, and 9, in which the web cl is made separate from theflanges, and the flanges are constructed by fastening the angle-irons eand f to opposite ends of the web.

Another form of the studs is shown in Figs. 7 and 8. Here the web,instead of being composed of a continuous piece of iron, is made up ofthe separate cross-bars (1 extending from the angle-iron e to theangle-iron f and secured in the position shown; also, of the cross-bars(1 secured as shown. The

bars d and (1 may be arranged as shown in Fig. 8, so that the same boltor rivet may answer to secure two of the bars to each of theangle-irons.

The studs are secured to the floor and ceiling beams, respectively, bythe an gle-irons g g, as shown in Fig. 1, having one flange bolted tothe floor or ceiling beam, as the case may be, and the other flangebolted to the web of the stud.

In general the fireproof boards will be applied as shown in Figs. 1, 2,and 3. h h 72. represent the boards of one partition. h represents theboards of the partition at right angles thereto.

It will be observed that every two adjacent studs are placed so thattheir flanges on the same side of the partition are directed toward eachother, as shown in Fig. 3.

It is obvious that after the studs are set up and secured in place, asshown in Fig. 3, the boards h can be placed in position against theopposing flanges of the studs 0 c from the side of the partition shownby arrow at, and that the boards 71,2 can be placed in position from theside of the partition shown by arrow y, or that they can be diagonallypassed through the space between the studs and drawn back squarely intoposition if it is important or convenient to have all the boardsdelivered on the same side of the partition. The boards 71 0f thepartition at right angles may be placed in a similar manner, the samestud 0 being used to secure the 'ends of the boards 71 and 72, byhalving or otherwise interlocking the ends of the boards together,'as inFig. 1.

The boards can be held in place by hooked bolts 1' or by large-headedwire nails 1', passed through the board and then clinched down over theflange f, as shown in Fig. 4, or by countersunk bolts '6 passing throughthe flange of the studs and through the board. There either of the firsttwo methods of fastening the boards is employed, the boards should bemade a trifle thicker than the cross-width of the stud, as shown in Fig.3, so that the plaster or hard finish which is applied to the boards maybe made to completely cover the ends of the bolts or nails, as the casemay be, as well as the flanges of the iron studs. "Where countersunkbolts, as 1' are employed, their nuts are let into the plaster-boards.

At a suitable height on the studs small brackets j j may be riveted,suitable for supporting a picture-1nolding, if desired.

In case a partition of more than a single thickness of boards is desiredthe construction shown in Fig. 9 may be employed. Here the boards h 71,are supplemented by the boards 71 lbs, separated, so as to make anairspace between, by the filled pieces 76 k k 70". It is evident thatsuch thick fire-proof walls as these last described would be very usefulfor large temporary buildings for great exhibitions, 8:0. The ironframe-work could be put up complete, with boards of suitable lengthrapidly fitted between the studs and fastened with large bolts, whoseheads and nuts may be left visible or not, as wished. The structurecould, moreover, be readily taken down without destroying the material.

I elaim- 1. A wall containing, in combination, a series of Z-formedstuds having their flanges turned alternately in opposite directions anda series of panels secured to said studs alternately from opposite sidesof said wall, substantially as described.

2. In combination, two walls forming an angle with one another and eachcomposed of a series of Z-formed studs having their flanges turnedalternately in opposite directions and a series of panels applied tosaid studs from opposite sides of the walls, the adjacent ends of thepanels at the union between the two walls interlocking, substantially asdescribed.

3. Awvall containing a series of Z-formed studs having their flangesturned alternately in opposite directions, in combination with a seriesof panels applied alternately on opposite sides of said wall, each ofsaid panels consisting of an inner and an outer thickness separated by afiller, substantially as described.
